Tracer study of the kinetics of dissolution of barium sulphate
Abstract
The dissolution into water of barium sulphate labelled with 35S has been studied from 10.5 to 35°C. The kinetics proved to be second order to at least 85 % saturation, the activation energy being 24.7 ± 0.8kJ mol–1. Diffusion control of the dissolution process was not observed.
